1. You measure your body temperature with a thermometer calibrated in degrees
Celsius and found the reading was 37 o C . What is the value in Kelvin ?
273 + 37 K = 310 K

2. Two rings are made of the same metal and have the same radius, but one is hollow and the other is solid at
room temperature. The temperature of both rings is increased by the same amount. Which ring expands more?

Answer : Both expands the same amount .

The property of matter that is most important in determining its state (i.e., solid, liquid, or gas) is
Matter change state at specific temperature. That is why there are such term as freezing point and boilling point of substance,
at wich the substance change states. There for, the important characteristic that determine the state of matter is the temperature.

Objects A and B are brought into close thermal contact with each other, but they are well isolated from their
surroundings. Initially TA = 0°C and TB = 100°C. The specific heat of A is more than the specific heat of B.
The two objects will soon reach a common final temperature Tf. The final temperature is...

Since heat will flow from higher temperature to lower temperature , heat will flow from B to A. In this process,
